Patented Mar. 26, 1918.

Application filed August 5, 1916. Serial No. 113,363.

To all whom it may concern:

Be it known that 1, ROBERT B. CoLnMAN, a citizen of the United States, residin at Los Angeles, in the countyof Los Angeles and State of California, have invented certain new and useful Improvements in Material-Compressing Machines, of which the following is a specification.

This invention relates to improvements in a material compressing machine, and particularly such as is adapted for the compressing of all kinds of comminuted material such for instance as sawdust, shavings, chips, straw, hay, feed pulp or the like, whereby such materials are brought into the form of sticks, blocks, briquets, etc. 'Sawdust, shavings, chips and the like when properly compressed form an excellent kind of fuel, thus utilizing materials which would ordinarily go to waste.

It is an object of the invention to produce a machine having ample power to tightly compress such materials as are above men tioned, means being provided for holding the materials until a proper length of stick or block has been formed, after which the stick is broken off and a binding means, such as wire, is twisted to hold the materials compressed and is cut off at the proper length.

It is also an object of the invention to provide a machine of this character in which the compressed material formed may be broken off and a binding wire fastened about the same, without the necessity of turning or twisting the separated sections of the compressed material, as has been necessary in devices for accomplishing such purposes heretofore.

t is a further object of the invention to provide a machine of the kind mentioned, in which a power plunger continuously forces and compresses the materials and in which stick dividing means employed for causing the breaking oil of the compressed mate rials at suitable intervals, a'wire twisting and cutting means being provided and operated automatically by the compressing mechanism for twisting the wires between the severed portions of the compressed material, the fastening of the wire being acconr plished in such a way that room is left therein to accommodate the expansion of the com- Figure 1 is a front elevation of a machine constructed in accordance with this inventlon.

The mechanism of the present invention is designed to compress loose or comminuted materials into composite solid form and especially materials that ordinarily would go to waste, such for instance as sawdust, shavings, chips and the like, or in fact any other materials which it may be desired to compress and bind in suitable form for various uses, and to pass a holding means around the compressed material to keep it in com pressed form, the holding or binding means having sufficient slackness to permit of considerable expansion of the material under various conditions of atmosphere or under the different conditions of material when dry or wet. The mechanism is particularly well adapted for compressing materials of the character mentioned to form fuel from materials that would otherwise not be in proper condition for use in the ordinary stoves or furnaces. Thus the materials are prefe ably made into sticks or briquets of various sizes and shapes. In the accompanying drawings preferred embodiments of the invention have been disclosed and the details and feature of the said invention will now be particularly described reference being had thereto.

In the said drawing, 12 indicates the main frame of the device having a transverse shelf or support 13 about midway of its height and a broad supporting base 1% at the bottom. The frame extends above the shelf 13 so as to form a standard 15 upon which is journaled a shaft bar 16 bearings 17 being provided therefor. The standard is preferably bifurcated at 18 and a large gear wheel 19 is secured to the shaft 16 so as to be revolubly mounted in the bifurcation. The gear 19 meshes with a pinion 20 which is carried by a powe shaft 21. The said power shaft extends to any suitable source of power and its rotation turns the pinion 20 and actuates the gear 19 in transmitting motion to the shaft 16. The shaft 16 projects at one end sufficiently far beyond the bearing 17 to have secured thereon a crank disk 22. The said disk 22 has a wrist. pin 23 projecting therefrom which engages a pitman 2 1, the lower end of which is connected with a plunger head 25 moving in guide bars 26 secured to the side of the standard 15. 25 has a depending compressing plunger 27 projecting therefrom and adapted to force loose materials into a die member 28 mounted upon the shelf portion 13 of the frame. The rotation of the shaft 16 by means of the gear 19 thus causes thevertical reciprocation of the compressing plunger 27 whereby sawdust or other loose material may be continually forced into and compressed within the said die 28.

The shelf 13 is provided with an opening 29 within which the die 28 is mounted. The upper part of' said aperture is provided with an enlarged portion forming a die supporting shoulder 30. The die may be of any de- T he said head sired construction but is preferably of such a nature that the materials may be compressed therein and the wires for binding the materials in compressed form, laid in grooves or kerfs in the sides of the composite stick formed. The said die is preferably made in two sections, one of which is rigidly fastened to the shaft 13 by one or more screw bolts 31, passing through a flange 32 at the upper edge thereto. The other die section is adapted to rock slightly in the opening 29, and is provided with a flange 33 tapered upon its under surface as clearly shown in Fig. 3. The aperture 29 is cut back slightly from its upper edge downwardly to permit the said. section to rock when desired. The lower portion of the section is adjustably held with respect to the other section by means of an adjustable screw 34-, the inner end of which bears against a socket at 35 formed in the outer surface of the die section. By applying a lever handle 36 to the outer squared end of the screw bolt 34:, the said bolt may be adjusted to permit the opening of the die sections to the extent desired. If it is found that the materials are held too tightly in the die, so as to be liable to become fastened or wedged therein a. light turning of the screw bolt 31 will ease up upon the die section and permit the materials to be forced on through the die. The lower end of the fixed die section is supported by an abutment bolt 37 for bracing the lower part of the die. The die sections are preferably provided with inner sections 38 and 39 which are provided with shoulders 10 adapted. to engage opposing shoulders 41 formed in the lower end of the die by the reduced bore thereof. Screws 12 hold the lining ection in place. V

In order to properly lay the binding wires in the material as it is compressed elongated blades 13 are carried in the lining sections 38 and project inwardly from the surface thereof, a sufficient distance to embed themselves in the composite stick of material formed, whereby kerfs or grooves 1% will be formed in the stick so of composite materials. VVires 16 are introduced through apertures 47 near the lower ends of the die sections, the said wires being thus directed to the kerfs 14: by the lower ends of the blades 13. Below apertures 47 hort blades 4.8 push the wires into the kerfs 44:. The wires from opposite sides of the die are twisted together at 4:9 and thus extend across the end of the (:lescending compressed stick and the said stick will push the wires along with it.

The repeated reciprocation of the com pressing plunger 27 operates to force a compressed stick through the die and out of the lower end thereof. The said stick enters the upper end of a gripping and separating mechanism which consists preferably of an opposed pair of semi-cylindrical jaws 50 which are preferably pivoted together at their lower ends as at 51. The lower ends of said aws are movably held in proper position by a bearing 52 formed in a cross bar or plate 53 carried by the base 14 of the machine. The said jaws are loose in the bearing 52 to permit the jaws to move freely up and down and to separate slightly when the jaws are to be opened. The upper ends of said aws are provided with inturned gripping ed es or flanges 5 L, theinner edges of which are usually serrated to form gripping projections or points as at 55. When the jaws are drawn together about the stick of materials compressed in the die, the flanges 5st will grip the stick and embed themselves in the material thereof, so that when the jaws are lowered they will cause the breaking of the stick at the point of on gagemeut with the flanges 5d and the broken section will be pulled downwardly. The broken section is carried downwardly a suitable distance to permit of the twisting of the wires e6 between the severed portions of the composite stick. The downward movement of the jaws 50 is usually limited by an adjustable stop 56 carried by one of the jaws and having a slot 5'? engaged by a clamping bolt 58, which passes through said slot. The desiredspace between the broken sections of the composite stick may be controlled by the adjustment of the said stop 56.

The jaws 50 are adapted to be raised and lowered at the proper time by means of a bifurcated lever 59 which is pivoted upon a cross rod or shaft 60 mounted at its ends in standards 01 of the frame 12. The inner biturcated portion of the lever 59 is made of suitablewidth to receive the jaws 50 and is pivotally connected with the said jaws by means of toggle links as at 63. The links are movably mounted on the outer ends of bars 64: which are riveted or otherwise fastoned to the said jaws 50. The links 62 ex tend beyond their pivotal connection with the lever 59 and their projecting end portions are preferably connected by springs 65, the action of the springs being to tend to fold the links 32 and draw the aws 50 together. This action however is controlled by the position of the lever 59 and when the inner end of the said lever is depressed it will move the links downwardly, causing them to pull. the jaws 50 together. When the bii urcated portion of the said lever 59 is raised a gain it will force the toggle levers 62 to move the jaws apart, a proper distance to release the composite stick from the grip ping flanges The outer end of the bifurcated lever is provided with an angular slotted portion (jdwhich engages by means of its slot ($7 a pin 68 which projects from one side oi a vertically moving cam member or rod 159. The cam rod 69 is movable up and down in the machine in conjunction with the reciprocations of i he plunger head 25. The said cam rod is not continuously moving however but is only brought into engagement with the said plunger head when it is desired to break off a section oi the com posite stick. The lilunger head 25 carries a rod actuating arm Q'O which projects past the rod 39 1" 011 one side thereof so as to be then engwd by a pivoted latch 71 connected by linl 2 with said rod. The said latch 71 is normally held out. of the path of the arm by means of a trip lever 73 pivotally mounted at 74 upon one side of the cam rod 69. The upper end of said trip lever is turned so as to project laterally and engage a hole or aperture 75 it'ormed in an arm 76 projecting from the latch member 71. A spring 77 fastened to the outer end of the arm '76 and connected with a pin or bolt 78 upon one side of the rod (35) tends to throw the latch 71 outwardly and into the path of the arm 7:) when the latch is released by the trip lever The arm 70 is also adapted to engage a bracket or stop member 79 projecting from one side of the rod as will be clearly apparent by reference to Figs. 8 and 9 of the drawing. The rod 69 is carried to the lower end or its stroke by the action oi the arm 70 against the stop it). The said rod will not be elevated again until the latch member '71. is released and it is thrown outwardly into the path oil. the arm 70. Upon the next depression of the arm 70 the latch member 71 will snap over the upper edge thereof and the upward movement of the arm 70 will carry the rod 69 upwardly and then downwardly again. While at the upper end of its stroke the latch member 71 will be nfested inwardly by a spring actuated bolt or plimger 80, carried by a housing S1 which supported upon a bracket 82- proje 11g from the frame of the machine. lt'hen the said latch member 71 is pressed inwardly the trip lever will again engage the apertures 75 for holding the latch member 71 in its normally folded position. The trip lever is moved by means o1 a bar83 pivotally connected at Setwith its lower end. The said bar projects from the cam rod 69 toward the gripping jaws and extends through a slot 8;"; in one of the jaws 5:). This end of the bar 83 is provided with a triangular portion or h id having an inclined edge or face 86 extending into the path of the composite stick of compressed materials which descends through the said jaws 50. hen the stick has attained the proper length. for breaking it oh? it will push the hto one side moving the rod 88 and trip lever 73 so as to release the said latch member T1. The inner end of the rod or bar 83 is morably supported by a link 87 which. is pivoted at its lower end to said bar a nd at its upper end to pair of projecting flanges 88 which extend from the jaws 50 on .ing position each side of the slot 85 as clearly shown in 3 and 9 of thedrawing. A pin 89 supporting the upper end of the link 87 may be adjusted to different heights by inserting it through any one of a series of holes 00 formed in the said flanges 88. The length of the broken sections of composite material may thus be modified and controlled. A spring 91 connecting the rod or bar 83 with the jaw 50 normally pulls the said bar inwardly and holds the trip lever in latch lockuntil'the stick of compressed materials has attained a. suitable length to force the bar 83 outwardly against the action of the spring 91.

The shape of the angular slot 6? in the lover iii; is such that when the cam rod 69 in its normally lowered position the weight of the jaws 50 'annot depress the said aws farther for a recess 92 formed in the lower end of the slot 67 is made of suitable depth to form a shoulder at 93 which must prevent the said lever from rising at its outer end until the pin 63 has been raised by the upward movement of the rod 69 as will be readily understood by reference to Figs. and 9 of the drawing. As soon as the pin engages the inclined surface 9-21: of the angular slot it will begin to raise the lever 59 and throw the lower end thereof outwardly for a short distance or until the jaws 50 have lowered the broken off stick section sufficiently to fasten the wires about the same. The remainder of the angular slot 67 will then be in approximately a vertical position so that the rod 69 with the pin 68 may continue to move upwardly to their full strokes without further moving the jaws 50. Upon the depression of the cam bar 69 again to the lower end of its stroke the pin. 68 will lower the lever 59, raising and opening the jaws 50, and the said shoulder 93 will be brought into position once more to chock the lever in position to hold the jaws 50 in readiness for another stick section.

The cam rod 69, is preferably prevented from moving without the positive action of the arm 7 0 and for this reason is passed near its lower end between a pair of spring bars which have friction pads or bases 96 secured upon their inner surface and adapted to grip the cam bar 69 between them. The tension of the bars 95 may be controlled by a bolt 97 connecting their free ends as clearly shown in Fig. 1 1. The gripping of the bar 69 by this mechanism is such that the said bar will remain in any position at which it may be moved by an arm 70, whereby the movements described will be made possible,

An important feature of this invention is that the binding wires which are pressed around the composite sticks formed in the machine may be twisted with sufficient slack to prevent their being snapped or broken when the materials expand for any reason.

This frequently happens if the wires are too tight and the compressed materials become moist or wet in any way. The twisting of the wires is accomplished by means of cooperating twisting and cutting members 96 and 97 which are mounted upon a plate or platform93 arranged and movablysup- )orted near the upper end of the jaws 50. The plate 98 is provided with guide recesses 99 and 100 forme l in its surface and suitable actuating pins may. project downwardly from the said members 96 and 97 so as to be engaged by a suitable mechanism for drawing the pins toward and away from each other. The plate 98 is journalcd in a recess 10:2 formed in a cross bar or platform 103 which is supported below the shelf 13 between the standards 61. The said plate 98 has a sleeve portion 101 which extends through the aperture 102 and sufficiently below the same to receive and have rigidly fastened to the lower end thereof a beveled gear 105. The beveled gear meshes with an actuated pinion 106 mounted upon a short shaft 107. The shaft 107 is journaled in the standard 61 and is adapted to be rotated by a bevel gear 108 which meshes with a bevel gear 109 carried by the lower end of an inclined shaft 110 mounted upon suitable brackets on the main frame of the machine. The upper end has secured'theretoa bevel gear 111 which meshes with an actuating bevel gear 112 secured upon a shaft .21. By this connection of gears and shafting the plate 98 is given continuous rotation when the machine is in operation so that the members 96 and 97 are carried around the upper ends of the jaws 50 continuously.

The pins 101 which control the movement of the cutter and twister carry members 96 and 97 depend from the lower sides of said members and normally engage a groove 113 formed in the upper face of the platform 1.03. The said groove 113 is preferably circular so that ordinarily when the plate 98 rotating the members 96 and 97 will remain in their outer positions. The inner wall of the groove 113 is interi-als forming gaps or passage ways 1141 on opposite sides of the said groove 113. An inner groove 115 is also formel in the said platform 103 and is connected by the passages 11-1 with the outer groove 113. Switch members 116 are pivoted at 117 in the said passages 11 1 and their free ends are so arranged that the switches may be thrown outwardly to the positions shown in Fig. 7 in which positions they will guide the pins 101. so as to carry them into the inner groove 115. When the switches 116 are in the positions shown in full lines in Fig. 7, the pins 101 will be guided through the passages 111 to the outer groove 113 again. The switch members 116 are controlled by arms 118 which are axially connected with however broken at v the said switch members .116, and extend below the shelf 103. said arms 118 with a cross bar 120 which in turn carried by the inner end of a thrust rod 121. The said thrust rod engages a hearing 122 formed in a bracket which depends from the shelf 13. The thrust rod 121 projects beyond the cam rod 69 a suiiicient distance to have a pin 124 which is carried by said rod engage a. cam mecha ism 125 upon the said cam rod 69.

The said cam mechanism comprises a part with guide flanges 126 and 12? formed upon one face of the device the tlange127 being broken away at intervals a suiiicient distance to receive a movable cam or switch member 128. Said cam is pivoted at 129 and its opposite ends are curved in opposite directions with respect to each other forming a substantially S-shaped cam. Pins 130 project through curved slots 131 in the base 01" the cam mechanism and sutliciently beyond the same to be engaged by springs 132 which are. riveted at their outer ends as at 133 to the said base plate. Stop projections 134.- keep the springs normally pressed against the said pins 130 as clearly shown in Fig. 10. The action of the springs is such that the cam 128 normally occupies the position shown in Fig. 9 of the drawing, but its ends may be pushed aside by the pin 1241 at cer-- tain points inthe operation of the cam mechanism. With the parts in the position shown in Fig. 9. when the cam bar 69 rises the pin 124 will be carried inwardly by the cam 128 and will cause the throwing of the switch members 116 outwardly. The said pin will move the cam 128 at its lower end so as to snap by the same wheuthe cam bar 69 has been elevated. to its full height. Upon the descent of the said cam bar the cam 128 will force the pin 12 rinto the outer part of the cam device. whereby the thrust rod 121 is drawn outwardly again and the switch members 116 are swung inwardly to their normal position.

The cutter carrying members 96 and 97 are formed with curved recesses at their in nor ends of greater width thanthe width of the wires 16 before they have been twisted. The curved portions 135 of said recess are of such shape that when the members 96 and 97 are carried toward each other by the drawing of the pins 101 into the inner groove 115 that the wires will be drawn together between the severed sections of the composite stick until they engage the reduced shanks 136 of cutters 137 which project from the middle portion of said recess. The members 96 and 97 being arranged one about the other will slide upon each other and the wires will be drawn together as shown in Fig. 5. With merely the shanks 136 of the cutters between them the rotation of the platform 98 when the wires are Links 119 connect the in this position causes the wires operated to be twisted between the broken ends of the compressed stick. The cutters have cutting edges 1381113011 the inner sides of their cutter heads 137, and when the said cutters are drawn apart by the pins 101 moving to the outer groove 113 the cutters will have a shearing action upon the said wires and cut them oil. Since the shanks of the cutters were rotated to twist the wires. the twisted portions will be of the same length upon each side of their cut ends. Half of the twisting portion will complete the binding and securing of the wires about the broken nit section of the stick and one hall will hold the w? es, which receive the lower end of the stick coming from the dies, together ready for the binding of the next section of the stick. The cutters being centrally located are also in position for the wires to be drawn together upon each side thereof so that the rotation of the cutters will twist the wires. The movement of the knives inwardly will only be caused when the composite stick has reached the desired length and the cam bar 69 has been elevated for accomplishing its various functions. The wires are usually carried by spools 139 pivoted upon the frame of the machine at any desired point so that the wires can be freely drawn therefrom into the dies through apertures, -17.

In the operation of the machine the plunger reciprocates continually. Material is fed in any desired manner to the die 28, a flaring hopper 140 mounted upon the upper end thereof facilitating the operation. Under the continued reciprocation of the plunger the materials will be forced into the die and compressed. into an elongated stick of substantially the shape shown in Fig. 12. In being forced through the dies, the wires will be laid in the kcrt's ell and then carried on downwardly between the gripping jaws 50. As soon as the lower end of the composite stick strikes the inner end of the bar 83 the trip lever will be operated for releas ing the latch 71 whereby the said latch will engage the arm and the cam bar 69 will be elevated and depressed again for causing the depression of the jaws 50 in breaking oil the lower end of the stick, and the operation of the wire twisting and cutting knives to sever the wires after they have been fastened about the upper end of the stick. By making the jaws 50 descend a considerable distance the wires can be twisted so as to leave a slack space at 141 within the upper twisted end thereof as shown in Fig. 12. This space may be made suiiicient to accommodate all swelling or expansion of the compressed materials and thus prevent a snapping of the wires. The materials thus compressed and bound up form an excellent fuel and the wires hold the fuel together so thatit does not fall apart and separate, while burnin The wires are prevented from breaking in the fire too quickly by reason of their being embedded for the most part in the kerfs of the stick. The embedding of the wires in the said kerfs is chiefly needed, however, for preventing the materials from curling out from under the wires as the sticks are burned.

The power shaft 21 is preferably capable of connection with a source of energy by means of any ordinary clutch mechanism as let-2 which bears against the sides of a pulley 1&3 mounted upon the shaft 21. A belt l t i extends from the pulley to any suitable source of power, not shown. The clutch mechanism is carried upon the shaft 21 and may be thrown into or out of pulley gripping position by a hand lever 14s").

It will be evident that many minor details of the device may be considerably altered within the scope of this invention and that mechanical equivalents may be substituted for some of the parts without departing in the least from the spirit of the present invention.

In machines of this character, as heretofore constructed, in twisting and fastening the wires between the stick sections, it frequently happens that both wires will not be twisted, but one will be twisted around the other, so that an insecure fastening results and the wire which is not twisted will slip out of the other. This is not possible with the wire twisting mechanism of the present machine, for the twisting shanks go between the wires as they are drawn together, and since such shanks are between the wires, one must be twisted just as much as the other. Sometimes in other machines heretofore used also the compressed sticks did not break at the proper point. In the present machine the gripping jaws positively insure the breaking of the sticks at the desired points and prevent the cutting of the wires at any but the right place.
